About

Twyn Carno is a residential ward situated on the northeastern edge of Caerphilly town. The area is characterised by modern housing estates and quiet suburban streets, with views extending towards the surrounding valleys. It functions primarily as a commuter area for the wider county borough, with local amenities centred around convenience stores and community facilities. The layout is defined by its position on the hillside, giving it an elevated aspect above the main urban centre.

A significant local feature is the large, man-made Twyn Carno reservoir, which is encircled by public footpaths and serves as a focal point for recreation. The area is bordered by open countryside and farmland, providing direct access to walking routes into the Gelligaer Common. This blend of recent development and retained green space shapes the ward's environment, with the reservoir's earth dam forming a distinct landmark within the suburban landscape.
